(Updated at 1:10 p.m.) Arlington County and much of the D.C. area could see upwards of 3-6 inches of rain between Wednesday night and Friday morning.

The National Weather Service has issued a Flash Flood Watch for the area that’s now in effect from 6 p.m. Wednesday to 8 a.m. Friday, warning of the potential for streams and creeks to flood.

From NWS:

THE FLASH FLOOD WATCH IS NOW IN EFFECT…

* FROM 6 PM EDT THIS EVENING THROUGH FRIDAY MORNING

* A POWERFUL LOW PRESSURE SYSTEM OVER THE MIDWEST WILL BRING PERIODS OF HEAVY RAIN TO OUR AREA TONIGHT THROUGH THURSDAY NIGHT.

* WIDESPREAD RAINFALL AMOUNTS OF 3 TO 6 INCHES ARE EXPECTED… WITH LOCALIZED SPOTS POTENTIALLY GETTING UP TO A FOOT OF RAIN. ADDITIONALLY… THE EASTERN SLOPES OF THE NORTHERN BLUE RIDGE AND CATOCTIN MOUNTAINS HAVE AN INCREASED RISK FOR GREATER TOTALS.

* HIGH POTENTIAL EXISTS FOR FLOODING OF SMALL STREAMS… AS WELL AS URBAN AREAS. ADDITIONALLY THERE IS A POTENTIAL FOR THE HARDEST HIT LOCATIONS TO SEE SEVERE FLOODING AND FLASH FLOODING.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

THESE NEXT FEW DAYS WILL BE A DANGEROUS TIME… REQUIRING MORE THAN THE USUAL AWARENESS… PLANNING AND PREPARATIONS.

IF YOU ARE NEAR STREAMS OR DRAINAGE DITCHES… KEEP AN EYE ON THEM AND BE READY TO QUICKLY SEEK HIGHER GROUND. WATER MAY RISE RAPIDLY.

CLEAR OUT STORM DRAINS.

THOSE PRONE TO BASEMENT FLOODING SHOULD PREPARE. COMMUNITIES PRONE TO FLOODING SHOULD PREPARE.

CONTINUE TO CHECK IN ON THE FORECAST FOR UPDATES.

WARNINGS WILL BE ISSUED FOR AREAS WHERE FLOODING IS IMMINENT. ENSURE YOU GET WARNINGS FROM THE NATIONAL WEATHER SERVICE THROUGH YOUR MOBILE PHONE AND OR NOAA WEATHER RADIO.

BE PREPARED TO TAKE ACTION IF A WARNING IS ISSUED FOR WHERE YOU ARE OR IF FLOODING IS OBSERVED.

ENSURE YOUR KIDS DONT PLAY NEAR FLOOD WATERS.

REMEMBER IF YOU COME ACROSS WATER CROSSING A ROAD… TURN AROUND DONT DROWN!

It is a homeowner’s nightmare: You come down the stairs in the morning to start the day with a cup of coffee only to step into a puddle of water on the kitchen floor. A puddle? In fact, it is pooling from a leak under the sink, and it is spreading.

Good morning! Now what?

“When they call us, we talk them through everything they need to do to stop the problem,” says Yael Goldshmid of Flood Damage Pro. “We give them instructions over the phone on how to turn off the main and to remove any electrical elements from the area.

“Then we promise to send a crew within 60 minutes of their call.” And that call will be answered 24/7.

Flood Damage Pro has been serving the flood emergency needs of commercial facilities and residential dwellings in Arlington for over 10 years, and by now their IICRC certified technicians have seen it all: Flooded basements, flooded kitchens, flooded bathrooms, flooded offices and more.

A water and fire damage specialist is crucial in early moments of water/fire-borne disasters as they are equipped with the technology and the knowledge to stop, repair and then begin the recovery process as fast as possible. This is important because of a secondary consequence of water damage: Mold.

“If water damage is not addressed in time, mold develops,” warns Goldshmid. “Sometimes we come to a house and the owners tells us there is a smell they can’t get rid of where the water damage was. We check and it’s mold. You can’t always see it, but it’s there.”

Update at 2:15 p.m. — Arlington is now under a Severe Thunderstorm Watch through 10 p.m. From the National Weather Service:

“SEVERE THUNDERSTORMS ARE LIKELY LATE THIS AFTERNOON INTO TONIGHT. THE MAIN THREAT IS DAMAGING WIND WITH LARGE HAIL AND ISOLATED TORNADOES ALSO POSSIBLE. THE GREATEST RISK WILL BE BETWEEN 6 PM AND 10 PM…ESPECIALLY ACROSS VIRGINIA AND THE WASHINGTON METROPOLITAN AREA.”

Earlier: Arlington and the D.C. region is under a Flash Flood Watch tonight.

Forecasters say heavy rainfall is expected and may cause localized flash flooding. The watch is in effect from 5 p.m. to 6 a.m. Friday. From NWS:

* FROM THIS AFTERNOON THROUGH LATE TONIGHT

* THUNDERSTORMS WITH HEAVY RAINFALL ARE EXPECTED LATE TODAY AND TONIGHT. REPEATED THUNDERSTORMS WITH HEAVY RAINFALL OVER THE SAME AREA MAY RESULT IN FLASH FLOODING.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

A FLASH FLOOD WATCH MEANS THAT CONDITIONS MAY DEVELOP THAT LEAD TO FLASH FLOODING. FLASH FLOODING IS A VERY DANGEROUS SITUATION.

YOU SHOULD MONITOR LATER FORECASTS AND BE PREPARED TO TAKE ACTION SHOULD FLASH FLOOD WARNINGS BE ISSUED.

A FLOOD WARNING MEANS THAT FLOODING IS IMMINENT OR HAS BEEN REPORTED. STREAM RISES WILL BE SLOW AND FLASH FLOODING IS NOT EXPECTED. HOWEVER… ALL INTERESTED PARTIES SHOULD TAKE NECESSARY PRECAUTIONS IMMEDIATELY.

DO NOT ATTEMPT TO TRAVEL ACROSS FLOODED ROADS. FIND ALTERNATE ROUTES. IT TAKES ONLY A FEW INCHES OF SWIFTLY FLOWING WATER TO CARRY VEHICLES AWAY.

DO NOT UNDERESTIMATE THE POWER OF FLOOD WATERS. ONLY A FEW INCHES OF RAPIDLY FLOWING WATER CAN QUICKLY CARRY AWAY YOUR VEHICLE.

Forecasters says a storm system that’s making its way north from Louisiana will dump 1-3 inches of rain and spawn some potentially strong thunderstorms (see Storm Prediction Center outlook, left).

Arlington Public Schools are closed today after an ice storm overnight.

APS announced the cancellation decision around 4:30 a.m, as most roads and sidewalks were still icy from freezing rain. Fairfax County Public Schools and many other local school systems made the same call, although D.C. Public Schools are only on a two hour delay.
